Triggering SystemExit

How SystemExit is raised and how to catch it.

python
# Triggering and catching SystemExit
try:
    raise SystemExit(0)
except SystemExit as e:
    print(f"Caught SystemExit: {e}")
    print(f"Type: {type(e).__name__}")

SystemExit is raised when raised by sys.exit(); used to exit the interpreter. Always catch specific exceptions rather than bare except clauses.

Handling SystemExit

Basic error handling pattern for SystemExit.

python
# Safe handling pattern
def safe_operation():
    try:
        raise SystemExit(0)
    except SystemExit:
        print("Operation failed gracefully")
        return None

result = safe_operation()
print(f"Result: {result}")

Wrapping risky operations in try/except blocks prevents your program from crashing.
